An obj ect is to provide a joint oi this charb acter which may beeasily,quicklyand cheaply prepared atthe factory andinstalled in the bell endof a cast iron or other metal pipe to be. shipped to the field andassembled to form a pipe line, without athenecessitypf m handling orpouringmoltenlead at the scene ofoperations; V i a The inventionprovides a preformed joint which may be readily installed ;in proper rform, within the bell, of vthe pipe, byuni skilled labor, the elements:inak ing up the joint being of such nature as to enablethe same tobeassembled at a minimum cost'and to'eflect a great saving'in theamount'oflead used therein,

Itwill be noticed that the internal diameter of ring 7 substantinhlythesame as the internal diameter of the mouthof the bell, so that thelower ends of the blocks may be driven down into the bell.

The inner wall of thehell is ,provided'with opposlteinlined portions 2land22, the por --2lyadjoining the beveledseat l9 and the portion 22terminating short of the'outer end of timimllysaidoutarend having anouter rib or shoulder 23 having its inner face beveled; "as shown 'at I1 A driving gland 2'5 as now placed around the upper, free end ofthe'mandrel l tg sai'd gland being freely slidable along the same, andifs a'dzpted to. *bedr-Wefl or :iorcel down: wardly, as bya'hydraulicpress, to drive the blooks'=to=the-pos1tionshown in Fig. .5 with fthelower-beveled e s 11 resting illp on thQ upper beveled fiaee o the ring.

To prevent dainage: during shipment, thejoint ma have suitable protective means applied thereto, such aswoodenblocks' or the like,.'as in Patents 1,270,309 and 1,648,494,12heprotective means being removed when it is desired to complete the jointwith the spigot of another section ofpipe. i t a The spigot is somewhatgreater in fthick} n'ess than the body of the pipe 16, ,asfshown at 33in Figs. 8 and 9,said increasedithi ck ness being partly on the insideand partly on the outside of the pipe, as shown. The inner thickenedportion is tapered off, as shown at 34: and 35*at the end of the spigot,while on the outside, the thickened portion is pro vided witha shoulder36 formed near the end by an inclined wall 37 extendinginto the body ofthe spigot. 7

hen the spigot is introduced into the bell to rest upon the roundedshoulder 1-7 of the latter, it willbe noted, by reference to'Fig.

8,. that the inclinedfwall 37 of the spigot is substantially parallelwith the aforesaid in= clined Wall 22 in the inner wall of the bell,"

. and that the blocks, prior .to the final calking" (Fig. v'lie flatagainst said wall 22 of the bell at an anglewhich locates the lower endsof the blocks flush with the inner circumferential edge of the innerlayer of jute, and it'will also be noted that the shoulder 36 on belowthelower or the spigot is; somewhat inner ends of the block's.

After the final calkin'g is 'completedjin' the field (Fig. 9), the leadisdriven within the mouth of the bell, as shown at 38, thus. driving theblocks downwardly and inwardly, causing moreof the lead to enteribehindthe rib or shoulder; 23 to straighten the locking neans at this point,andcausing the por- .tion 31. to be extended fartherdownbetween.theblocks and the outer fac elo'f the spigot.

' Furthermore, the fins or webs .32 are, driven V blocks to; crowd.therntogether tightly' at their lower ends. and to stop all leaks at thea greater distance in between the adjacent mouth of the bell.

i As the blocks are thus forced, they are caused to tilt furtherbykreason of their contactwiththe aforesaid inclined wall 22 of the belland also by reason of thecontact oftheir beveled lower ends with a theaforesaid inclined upper surfaceof the inner ring'18 of tightlycompacted jute, fwith the result that y the said inner ring 18 is:depressedtightly to hug the blocks, and the lowerends ofthe blocks arebrought intoa'ctuaI engagement with theshoulder 36 ofi the spigot us"prevent" any: relative longitudinal irnovement of the two "sections ofpipe; #Also, the inner jfaoes offthe lower portions jof.*theblocks arefcrowded intoltight engagement with the in? clin'e'd Wei-1370fthespigot. .Thisaction on lof.

the'blocks'causes a crowding and tightening otiallelement's' of the"joint withithe res lt. that the likelihood'of leakage is reduced to' aIiiininiu in and especially when the blocks become water-soaked andfurther expanded-' i The. pipe j Ointfherein' described is'cIaini'ed fin a divislonalapplication, filed'Jun'e 7 1932.

H F rom the foregoing it will be seen that a preformed "pipeejoint hasbeen providedwhich will eii'ect a: great saving by the utili'za v.tionoiiwo'oden'blockswhich maybe produced at 'ainuch less? cost thanserviceable wedges made of metal. j and have the -further advantage ofswelling 'toform a complete ringof wood to prevent leakage. Itwill''also be seen that the block's, by reason of their direct engagement atthei'r inner ends with'a shoul- 1 der on thespigot and, at their outerendswith a. shoulder in the bell, will effectually prevent longitudinalmovement of the spigot within the bell when the pipeline is underpressure; Itwillfbe further seen that a great saving is effected byreason of the fact that with the arrangement of parts as' in the"presentinvention, but onelayer of jute or other fibrous "materialisusedfor the innerseah'and' consi"derab 1y less 'lead isirequire'd toform the oliterfsealof the joint, as part of the; space usually occupiedby suchleadfrin gs at the mouth of the .bell, is herein occ-upied by.the upper ends-lofthe blocks.

Moreover, it is not indispensable that all thegfeatureslof the'invention'. be used. conj oint ly, since; they.
